Transition metal phosphides and sulfides are crucial for the hydrogen evolution reaction (HER) but face challenges in water dissociation kinetics and active site density. A CoNiPx/NiSx/MoS2/NF heterostructure was developed to optimize water dissociation and electron transport, improving catalytic activity with a low overpotential and high durability. The hierarchical design enhances water adsorption at sulfur sites and regulates H∗ intermediates at molybdenum centers. The study aims to guide the development of cost-effective catalysts for efficient HER. The pursuit of green hydrogen production is essential for sustainable energy development, and alkaline water electrolysis is a key method. The scarcity of hydrogen protons in electrolytes leads to sluggish kinetics, emphasizing the importance of catalyst efficiency. Transition metal sulfides like MoS2 show promise for HER but require enhanced active site density. Strategies like heterostructure construction and surface modification boost HER performance, highlighting the potential of transition metal sulfides. Electrodeposition techniques have shown success in enhancing catalyst structures, leading to improved HER activities. Overall, the study provides crucial insights for advancing non-precious transition metal catalysts and optimizing hydrogen production efficiency.
